A police source said three suspects had been arrested so far. A justice source said at least two had been killed, including a woman who blew herself up with a suicide belt.
The source said the operation was still under way shortly before 8 a.m. (0700 GMT) and police were still trying to “neutralize” two more suspects.
“There are men from RAID shooting from the rooftops,” Djihane, a neighbor, said on France Inter radio. “We’ve been told to lie on the floor and not go to the windows.”
Three policemen and one other person were hurt during the operation. There was no immediate official confirmation.
It happened so fast.
